Inventor: MATSUMOTO TSURUYOSHI
IPC: C03C25/105
Filed: 1988-08-01
Abstract: A cladding material for an optical fiber is described, which is made of a polymer comprised of (A) 10-90 wt.% of a long-chain fluoroalkyl group-containing monomer of the formula:
     wherein F is F, CH 3  or CFa, and n is an integer from 5 to 11, (B) 5-90 wt% of a short-chain fluororalkyl group-containing monomer of the formula:
     wherein Y is as defined above, X is F, CH 3  or CF 3 , and m is an
     integer of from 1 to 4,   and (C) 0-50 wt.% of other copolymerisable monomer. The   melt flow index indicating the amount in gram of the polymer   extruded for 10 minutes from a nozzle with an orifice having an   inner diameter of 2mm and a length of 8mm under the conditions of a temperature of 230°C and a load of 5kg, is not    larger than 30. The material can be used as cladding in a core-clad optical fiber in which the light transmittance retention ratio la/lo when wound satisfies the requirement represented by the following formula:
     wherein lo stands for the intensity of transmitted light measured when parallel light having a specific wavelength is made incident from one end of the optical fiber having a length of 10m and emitted from the other end thereof, and la stands for the intensity of transmitted light obtained when the optical fiber is wound by 100 turns on a rod-shaped mandrel having a diameter of 10mm and the measurement is conducted in the same manner as described above.

IPC: G11B27/13
Filed: 1988-09-01
Abstract: In a record disk apparatus which has a motor-driven spindle (31) for removably receiving a record disk (30) having an index mark as the sole circumferential position indicator, the spindle (31) is provided with a tachometer member (31T) with marks angularly displaced a distance equal to the disk storing a predetermined number of bytes on the record tracks. A byte counter (12) counts byte periods and is reset by each of the tachometer marks for indicating offset of the marks from the index signal. A register (17) stores the offset as determined by the count in the byte counter at index time. A segment counter (20) counts tachometer pulses for indicating which of the segments are currently being scanned on the record disk. The segment count when coupled with an offset indication provides true rotational position to a byte granularity. The index pulse resets the tachometer counter to zero. The segment counter (20) has a modulus equal to the number of groups of bytes (segments) in each of the record tracks.

Inventor: KOBAYASHI KOUJI
IPC: G01P13/00
Filed: 1988-10-27
Abstract: A velocity distribution measurement apparatus directs light at an object(8), detects scattered light from the object, photoelectrically converts the light and subjects it to signal processing to obtain velocity distribution characteristics of the object, by detecting a speckle pattern(13) formed by interference between rays of light scattering from points on the object. The apparatus consists mainly of a laser beam source(1); an optical deflector(4) for scanning the laser at a certain frequency; an optical system(7) for projecting the light scanned by the deflector onto the object; a detector(12) for detecting the speckle pattern; and signal processing means(15) for analyzing detector outputs to establish the speckle pattern variations for each scanning frequency at which the optical deflector performs scanning, in order to obtain information on velocity distribution in the object. The optical system is easy to adjust, and measurement and processing can be accomplished in a relatively short time.

Abstract: A closed circuit interactive television system (10) provides a multichannel television signal from a localized head end (12) which is used for indi­vidualized interactive selections by a plurality of users (22, 24, 26). Each user station contains a con­ventional television receiver (32a, 32b, 32c) and a smart box or interface and selection device (30a, 30b, 30c). The smart box or interface and selection device (30) is disposed between the television receiver (32) and the RF distribution amplifier (36). The number of user stations (22, 24, 26) on the system (10) is virtually unlimited. The system (10) provides the audio/video television signals (14, 16, 18, 20) in at least frame accurate synchronization to enable seam­less video switching between channels, which seamless­ness is enhanced through the view of a pair of tuners in the interface selection box (30a, 30b, 30c) which are alternately commanded to pretune to the channel of the next actual choice made prior to the changeover under control of a microprocessor in response to command signals embedded in the television signals being received.

Abstract: The invention relates to a vehicle tyre having a carcase which is embraced by two bead cores, the bead cores consisting of rigidity carriers such as plastic filaments and/or metal wires and it being possible to turn up the beads. In order to improve the objects required of the beads without adversely affecting their facility to turn up, it is proposed that the surface of the rigidity carriers of the bead cores prevents adhesion to vulcanised rubber, at least when the rigidity carriers are moistened in the vulcanisation position of rubber, so that each rigidity carrier is individually rotatable about its longitudinal axis with respect to the surrounding bead rubber. <IMAGE>

Title: Verfahren zum Betrieb eines Elektronenstrahlmessgerätes

IPC: H01J37/073
Filed: 1989-09-22
Abstract: In modernen Elektronenstrahlmeßgeräten wird die thermische La/B6 bzw. Feldemissionsquelle durch einen mit einem gepulsten Laserstrahl beaufschlagte Photokathode ersetzt. Da die Breite der Photoelektronenimpulse etwa der Breite der Laserimpulse entspricht, sind diese Geräte insbesondere für stroboskopische Messungen in schnellen Gallium-Arsenid-Schaltungen geeignet. Der apparative Aufwand zur Erzeugung der Photoelektronenimpulse ist allerdings beträchtlich, da Mittel zur Verdoppelung der Frequenz des primären Laserlichtes erforderlich sind. Es wird deshalb vorgeschlagen, die Kathode des Elektronenstrahlmeßgerätes mit Photonen der Energie EPh<W (W:= Elektronenaustrittsarbeit des Kathodenmaterials) zu bestrahlen und die Austrittsarbeit mit Hilfe eines äußeren elektrischen Feldes soweit zu reduzieren, daß Photoemission, aber noch keine Feldemission einsetzt.

Abstract: A transmission system in which a suitably modulated speech or data signal is combined with a low bit rate (100b/s) spread spectrum signal and transmitted simultaneously on the same channel with the modulated speech lying within the bandwidth of the spread spectrum signal. 
     At a receiver the modulated speech or data signal is demodulated and the modulated speech or data signal together with the spread spectrum signal are applied to a multiplier in which the spread spectrum signal is despread. 
     A code synchronising signal may be included in the modulated signal prior to transmission and when recovered in the receiver, the synchronising signal is applied to a pseudo-random code generating means. The transmission system may include a text transmission system in which case the low bit rate signal comprises pages of data. A number of pages may be transmitted simultaneously by spreading the data associated with each page by orthogonal psuedo-random codes.

Abstract: In a radio communication apparatus for selectively receiving a call signal, a comparison section (20) receives, in cooperation with a P-ROM (19), the call signal as a received signal. Responsive to the received signal, a counter (211) counts up an initial count to an increased count one by one to produce a count signal representative of the increased count. Responsive to the count signal, a control section (21) controls a controllable volume of an audible tone which is generated by a tone generator (23, 24). The control section may be connected to a light emitting device (25, 26) for emitting visible light. When a reset switch (27) is operated, the control section makes the tone generator stop generation of the audible tone. The controllable volume may be controlled by operation of a silent mode switch (28) and/or a volume mode switch (29).
